Article Abstract
Osteoporosis is an increasing concern in the aging population worldwide, culminating in increased economic concerns and diminished quality of life. Similarly, disturbances of lipid metabolism and adipocytes accumulate more and more in western societies and need solutions. Adipocytes have recently attracted much interest in relation to their endocrine products, one of which is adiponectin, normally associated with beneficial effects on cardiovascular health, inflammation, and cancer. In this study, we have investigated the effect of AdipoRon, an adiponectin receptor agonist with reported anti-osteoclastic properties, on the development of osteoporosis in two different preclinical models. Contrasting to our initial hypothesis, AdipoRon treatment accelerated metabolic changes and bone loss in both models. However, AdipoRon rescued bone marrow adipocytes presence induced by glucocorticoids. Investigations on adipocyte differentiation revealed that AdipoRon potently changes adipocyte identity, by exerting opposite effects on adipocyte-gene induction depending on the time point and duration of stimulation. In conclusion, adipocyte-derived Adiponectin deserves further investigation as an autocrine mediator in musculoskeletal research.

Adrenal lipomas are benign tumors containing ectopic adipose tissue in the adrenal gland, an organ that normally lacks both adipocytes and their progenitors. The origin of this ectopic fat remains enigmatic, and the absence of a genetic animal model has hindered its investigation. Phosphatidylinositol 3,4,5-trisphosphate [PI(3,4,5)P], a key signaling lipid that regulates cellular growth and differentiation, is tightly regulated by the lipid phosphatases PTEN (phosphatase and tensin homolog) and SHIP2 (SH2-containing inositol phosphatase 2).

In the current in vitro experiment, we fabricated and characterized placenta/platelet-rich plasma (PL/Pt) composite scaffolds and evaluated their effect on differentiating adipose stem cells (ASCs) into insulin-producing cells (IPCs) in vitro. The human placenta (PL) was decellularized (dPL), characterized, and digested in pepsin. PRP was extracted using a two-step centrifugation process and then freeze-dried.

Cultivating fat for edible tissue presents significant challenges, due to the high costs associated with growth and differentiation factors, alongside the poor viability of adipocytes resulting from cell clustering. Additionally, there is a gap in research regarding the rapid accumulation of fats within cells. To that end, this study presents the development of a biodegradable soy protein colloidosome system for an efficient application: direct delivery of oils into bovine satellite cells, enabling rapid intracellular fat accumulation without the need for adipogenic differentiation.

Introduction: Delayed wound healing remains a significant clinical challenge under diabetic conditions, characterized by chronic inflammation and impaired angiogenesis. Traditional treatments show limited efficacy, highlighting the urgent need for innovative therapeutic approaches.
Methods: This study investigated the therapeutic potential of exosomes derived from subcutaneous adipocytes (Adipo-EVs) using a diabetic mouse model.
